A sugar cane piler having a mechanical spring suspension device connected between the piler and the front end of the loader, the device including a precompressed spring to absorb a major portion of the weight of the piler and reduce the force of the piler acting on the ground. The device permits the piler to readily float over the ground and minimizes penetration of the piler’s tips into the ground.

A system for handling bales of feed includes a freight trailer with a tongue that can be offset laterally to cause the trailer to follow a path to one side of the path of a tractor to permit a front-loading device on the trailer to engage bales of feed and raise them onto a load-carrying platform of the trailer. The platform is tiltable downward to the rear to induce sliding movement of loaded bales, and to release said bales in a vertical stack. The platform is provided with a device to grip th…

This device is for an air operated safety latch designed to hold a folding pole trailer in its stationary or folded position when traveling. The device is comprised of a housing which supports jaw members which can move from an open to a closed position when a pole or other longitudinal member is placed between the jaw members, springs attached to each jaw member, a pivot arm attached to a latch block which locks the jaw members in place when the jaw members are closed, a spring to pull down on …

A precision robot apparatus (10) is disclosed which has an arm supporting cylinder (16) capable of being moved vertically by means of a lead screw (24) which rotates within a lead screw nut (38) attached to the arm supporting cylinder (16). A linear guide rod (44) is positioned parallel to the arm supporting cylinder (16) with an anti-rotation plate (42) therebetween. An arm drive belt (74) transfers rotational power from the linear guide rod (44) to the arm supporting cylinder (16). Rotational …

Structure for and method of die transfer. The structure comprises low friction bearing structures set into elongated T-slot bars secured in parallel, transverse spaced apart relation on a bolster plate and a die transfer truck table top actuable in response to the table top being raised to the level of the top of the T-slot bars with the table adjacent the bolster plate to raise a die positional on either the truck or bolster plate and facilitate universal movement of the die in a plane parallel…

An extendable boom fork lift vehicle is disclosed wherein the bottom and its actuator are positioned over the rear axle of the vehicle such that the weight of the frame between the front and rear axles and behind the rear axle may be reduced. A modified boom and jib are also described wherein the jib may be selectively fixed relative one telescoping member of the boom. A light-duty carriage is provided to operably engage and articulate a secondary heavy-duty carriage.

In a coin sorter of the inclined ramp type the inclined ramp has the usual support surface (2) along which the edges of the coins roll, and the usual coin face support surface (3). The support surface (3) is provided both with apertures (6, 7, 8, 9) of progressively increasing size going down the ramp, for coins of the appropriate size to fall through, and with a set of peeler knives (14, 15, 16, 17) at varying distances from the edge support surface (2) for tipping other coins, according to the…

A vehicle mounted roll-off hoist having a main hoist frame pivotally mounted at its rearward end to a vehicle such as a semi-trailer or truck, and including a pair of hydraulic lift actuators adapted to move the main hoist frame between a horizontal position and a rearwardly inclined position. A hydraulic actuator apparatus is provided for pulling a container onto the main frame of the hoist or setting off the container from the hoist. An extensible and retractable stop carriage is slidably conn…

A method and apparatus for forming a tie pattern of bales on a stacking table of a bale wagon. The method includes the steps of receiving a first array of longitudinally aligned bales on the stacking table, fixing the outermost or flanking bales of the first array for pivotable movement about a point, removing the bale or bales extending between the flanking bales of the first array, and inserting a series of a second array of longitudinally aligned bales generally midway between the fixed flank…

A material handling platform is pivotally attached to the front of the material transport vehicle. Actuator means raise and lower the platform. The platform is arranged to tilt relative to the vehicle about a horizontal pivot at the front of the vehicle. A turntable is mounted on the platform. The material handling platform positions roof supports in an underground mine adjacent a long wall mining machine. The roof supports are transported by the material transport vehicle carrying the material …
